BURBANK, Calif. (AP) - We'll have to wait until next summer to see what's up with Harry Potter and his wizard friends. "Harry Potter and the Half-Blood Prince" is being moved from November to next summer. It'll open July 17 instead of November 21. Warner Brothers says the writers' strike changed the dates when other movies would be released and created a good slot for this fifth Harry Potter film. The studio says their movie was progressing on schedule and could have been released in November, if they wanted.
